You didn't italize or mark the phrase, but I see one good candidate:
"The circus animal trainer" is in a way another name given to Mervin, a kind of "renaming" him: this is called an appositive phrase, so if this was the phrase appositive phrase is the answer! (also, I don't see the other phrases here).
The correct answers to the questions are:
3. D. Theirs - This is the third person plural possessive.
4. A. Common - This is the kind of adjective that is used most frequently in ordinary speech or writing.
5. B. object - This is what a noun that completes an action is called.
